SPECIFICATION forming part of Letters Patent No. 477,594, dated June 21, 1892.

Application filed October 31, 1891i. Serial No. 410.493. (No model.)

To all whom it may concern: V shoe to cause it to pass through the screen at Be it known'that I, THOMAS J. HATFIELD, a the proper rate. The shaft D has at each end citizen of the United States, and a resident of a doWnwardly-projecting lug or arm I), which Dublin, in the county of Wayne-and State of is pivotally secured to the inner face of the Indiana, have invented certain new and use-1 sides of the casing. At one end said shaft 55 f ul Improvements in Grain-Cleaners; and I do has also a stud or pin b',which projects through declare the. following to be a full, clear, andj an oblong slot 19 in the frame and has conexact description of the invention, such as will nected therewith a rod or link E, which at its enable others skilled in the art to which it ap-f opposite end is connected to any one of a se-' to pertains to make and use the same, reference ries of apertures in a pivoted arm or lever E, 60 being had to the accompanying drawings, and connected to a lugc on one side of the lower to letters of reference marked thereon, which shoe F, so that as the latter shoe is vibrated form a part of this specification. reciprocally, as hereinafter described, a vi- Figure 1 of the drawings is an elevation bratory movement will be imparted to the showing one side.

This board combination of parts, as hereinafter specified is for the purpose of carrying the grain to and 75 and claimed. discharging it over the rear end of the lower In the accompanying drawings, the letter shoe, in order that it may receive the full A designates the frame or casing of. the ma benefit of the screens therein. By the manchine. I ner in which the shoe 0 is supported, as shown I3 is the blast-fan, having the usual curved and above described,it may be removed from 80 casing and driven by a crank-gear and pin the frame at any time without necessitating ion, as shown, or by other suitable means. the removal of any rods, bolts, or screws.

0 is the upper shake or chaff shoe, in which H represents the hopper, supported at its is removably held a chad screen or riddle 0. forward end upon the cylindrical blast-wheel This screen is shown as designed to be recasing, and at its rear ends having the side 85 moved bya vertical instead of alongitudinal arms 77., which rest on the upper edge of the movement and is held in place by the end side portions of the frame on either side of piece 0 of the shoe. The lower or rear end of the shoe and which are held in place by strips this shoe is supported in the side brackets Ct 72/ of the frame. The hopper is held from of the frame. These brackets are made verslidingoff the rear of the machine by the stops c tically adjustable by a slot a and a set-screw 71?, which are engaged by the ends of the arms h. a to provide for the vertical adjustment of H is the adjustable slide for the hopper, the lower end of the shoe. The forward end working in grooves in the sides thereof. T0 of the shoe is supported on a transverse vione of the arms h is pivoted one end of a rod bratory bar or shaft D by means of abearing- I, which at its center has a connection 2' with 5 block D on the shoe, having therein a series said slide, its opposite end being held in a of bearings cl. The object of this adjustakeeper 1. By the operation of this rod. said bility is to render the shoe adapted to differslide may be raised or lowered to permit the cut kinds and qualities of grain requiring a adjustment for the desired feed. The hopper greater or less degree of inclination of the 11 may at anytime be lifted off and removed 10C) when it is desired to clean the machine or for convenience in transportation.

In the lower shoe F is a series of graded removable screens or riddles f, f, and f The screens f and f are provided at their discharge ends with a deflector-strip g, so arranged that the said screens will d'ischarge at opposite sides. The lower screen f has double deflector-strips g, by means of which said screen is caused to discharge at the center. The screen f separates the first grade, the screen f the second grade, cheat, and cockle-seed, and screen f 2 the clover-seed. Any finer seed, as timothy, will fall through screen f so that each class of seed is separated and discharged by itself at one operation. The loweror discharge :end of theshoe F is supported by hangers K,one on each forward end post of the frame. Said hangers at thei'r'lower ends carry each an anti-friction roller 7r,1u pon which rest and travel thecnrved or cam surfaces Z of blocks'or lugs L, secured to either side "of the shoe.

On one end of the blast-wheel shaft is a disk M,'having a wri-st-and-pitman connection M r with a longitudinal bar or lever .N, pivoted beyond its center to one side of the frame at n. The opposite end has a vertical arm N, which is connected by a rod or link 0 to a vertical :lever P, pivoted at its lower end to the frame and at its intermediate portion tof a lugor projection pen the shoe F. It will? be seen, through the above connection, that when the blast-wheel is turned a vibratory reciprocating movement will be imparted to the shoe F, andzthereby to the shoe 0.

By-means of the cam-blocks L, which travel on the rollers lc,.a vertically-oscillating movement will also be imparted to the .shoe F., The 'hangers K are each secured in place :by a set+screw K which passes through an -ob-. long slot therein, thereby providing for the vertical adjustment of the lower end of the' shoe I according to the character of the} grain it is desired to clean.

he blast from the wheel 13 is arrangedto? enter the .machine bet-ween the upper andi lower shoes, and at this point I provide aji wind-board R, hung on a rod or shaft 0, .projectin-g through the frame at one end and provided thereat with an adjusting-screw 'S. By means of thisboard a direct blast may be applied in a straight line, or by setting the 1 board at an angle the blast is deflected up and down, which is more effective, as the upi ward blast more thoroughly removes the chaff while the downward blast more effectually removes the finer particles of dirt and foreign matter.

The ease and convenience with which the hopper, chaff-shoe, and screens may be removed, owing to the construction and arrangement above described, is an important feature of the invention, as is also the adj ustability of the shoes and the means for changing their vibratory movement for different qualities of grain.

Each of the screensf, f, and f being different, if removed for any purpose, cannot be placed back in the machine-otherwise than in correct position, this doing away with the difficulty experienced in following instructions for the correct arrangement of screens by any one unfamiliar with the use-of such devices. Having described this invention, what I claim as new, and desire to secure byLetters Patent, is

1. In agrain-cleaner, an "endwise and vertically adjustable upper shoe having a vertically-removable screen 0 and a fine-mesh wire grain-board secured thereto and located under the upper portion of said screen, substantially as specified.

2. The lower 'shoe having the series of graded screens therein and the independent discharges therefor, the lower end of said shoe having the convex bearing-blocks, one

at each side, and the hangersadjustably se- N, a vertical lever P, pivoted .at its lower-end to the frame and at its intermediate portion to the lower shoe and connected by a link to the said arm N, and a vibrating connection between the opposite side of said shoe and a transverse loose shaft upon which one-end of the upper shoe issupported, substantially as In testimony whereof I affix my signature in presence of two witnesses.
